au_user_mask

Synopsis

Description

The au_user_mask() function reads the default, system wide audit classes from
audit_control(4), combines them with the per-user audit classes from the audit_user(4) database, and
updates the binary preselection mask pointed to by mask_p with the combined value.

The audit flags in the flags field of the audit_control(4) database and
the always-audit-flags and never-audit-flags from the audit_user(4) database represent binary audit classes.
These fields are combined by au_preselect(3BSM) as follows:

mask = ( flags + always-audit-flags) - never-audit-flags

The au_user_mask() function fails only if both the both the audit_control(4) and
the audit_user(4) database entries could not be retrieved. This allows for
flexible configurations.

Return Values

Upon successful completion, au_user_mask() returns 0. It fails and returns -1 if
both the audit_control(4) and the audit_user(4) database entries could not
be retrieved.

Notes

The au_user_mask() function should be called by programs like login(1) which set
a process's preselection mask with setaudit(2). getaudit(2) should be used to obtain audit
characteristics for the current process.

The functionality described on this manual page is available only if the
Basic Security Module (BSM) has been enabled. See bsmconv(1M) for more
information.

The au_user_mask() function is Obsolete and may be replaced with equivalent functionality
in a future release.
